TUCSON, AZ (Tucson News Now) -
A detail incident report filed by the Pima County Sheriff's Department specifies where and how a 13-year-old girl's body was found in the middle of the desert near Avra Valley.

Maribel Gonzales' body was found along Trico Road near Avra Valley Road on June 6.

There has been no word of suspects involved in Gonzales' death, according to PCSD, as the investigation is still ongoing.

The Pima County Medical Examiner's Office has completed an autopsy report but the cause of death is pending, according to the office's records department.

A 49-page incident report obtained from PCSD details detectives' and deputies' accounts of how they located Gonzales.

The records state that drag marks along the road led them to Gonzales' nude body, which was lying face down under a mesquite tree.

Detectives stated that the body was underneath two vehicle tires. A concrete pit filled with used vehicle tires was approximately 50 feet away from the body.

Investigators first got the tip from a woman who was driving south on Trico Road on June 6. The report stated she noticed suspicious drag marks on the roadway leading into the desert and followed the marks until she reached the body covered with the tires. Upon lifting a tire, she noticed the body underneath and called 911.

The woman told deputies that she noticed a newer silver pickup truck near the area in late May and that it was "tucked away in the bushes in the area where the human remains were found" for about a week.

Detectives took photos of shoe prints located around the drag mark path and took a wide brimmed camouflage hat, located on the side of the roadway, as evidence.

Gonzales' body was sent to the Pima County Medical Examiner's office where an autopsy was conducted on June 9. Forensics technicians retrieved Gonzales' anchor necklace and observed her butterfly tattoo, which was on the upper left chest near her clavicle.

Those conducting the autopsy, however, were unable to determine the cause and manner of Gonzales' death at the time and further investigation was required, the records stated.

Detectives documented several calls and interviews that stated the butterfly tattoo and anchor necklace, as shown in the media, belonged to Gonzales.

Other interviews with Gonzales' classmates and friends stated that she was supposed to go to a friend's house at one time, but never showed up and was missing.

Another interview with Gonzales' classmate who attended Allsport Academy, stated that she was unaware of anyone who would harm the teenage girl.

The classmate's mother also pointed out to detectives that Gonzales' mother, Valerie Calogne, was recuperating at the University of Arizona hospital after being in a hit-and-run accident on January 1.
